Hi Anstis,
I'm creating a rule engine which is basically a SQL query executor. for
that i need to have a drool
file where i can add new rules to build the different query criteria.
user should be able to create new selection criteria.
is there any way that i can define sql queries in side the drool files.
thanks

Let me see if I understand correctly.
You want the user to be able to define the SQL query (table, field list,
predicates) and have the resulting SQL executed within Drools?
Is this your only requirement for the rules engine; if so have you
thought a rules engine might not be your best option.

The best I think you could achieve would be something like this...
Global ExecuterService es;
rule "execute some SQL"
when
$q : Query()
$f : Fields(query == $q)
$t : Tables(query == $q)
$p : Predicates(query == $q)
then
es.execute($f, $t, $p);
end
Still not sure if a rules engine is your best option, if I understand
your use case correctly.
